Hello, again.
I forgot, but the subject line also says "same axes", not just same axes
scale.
If you want all densities on the same graph, use ?matplot (matrix plot).

Hello,
Something like this?
sag <- matrix(rnorm(1e3 * 9), ncol = 9)
d.list <- apply(sag, 2, density)
xrange <- range(sapply(d.list, function(d) range(d$x)))
ymax <- max(sapply(d.list, function(d) max(d$y)))
op <- par(mfrow=c(3,3))
for(i in 1:9)
plot(d.list[[i]], xlim = xrange, ylim = c(0, ymax))
par(op)
Hope this helps,

Good Evening-
I have a set of nine scenarios I want to plot to see how the
distribution
is changing, if one tail is getting larger in certain scenario,
currently I
am using this code
colnames<-dimnames(sag_pdfs)[[2]]
par(mfrow=c(3,3))
for(i in 1:9) {
d<-density(sag[,i])
plot(d,type="n", main=colnames[i])
polygon(d,col="red",border="grey")}
where sag is a 7305x9 double matrix and 9 different scenarios. I want
to be
able to compare the distribution using the same axes scale.
Can anyone help?
Thanks
Meredith LaBeau
